Log message:
tee(1): increase I/O buffer size from 8KB to 64KB
64KB strikes a good balance between space and time on today's
machines. Buffers smaller than 64KB waste more time in userspace
traveling to and from the kernel. Buffers larger than 64KB do I/O a
bit faster, but the performance improvements rapidly diminish at a
steep memory cost.
Discussed with millert@ and deraadt@. Positive feedback from Geoff
Steckel.
